The OHAUS Achiever™ 5000 mechanical mixers are designed for efficient and precise mixing as well as safety and ease of use in all conditions. The hermetic design features IP54 protection and ensures safe mixing even in the most demanding applications. The keyless handle and programmable speed increase allow for easy setup and safe mixing to protect the sample and user. Five models are available with torques up to 200 Ncm and capacities up to 100 l.



  • The brushless motor and torque compensation technology guarantee high efficiency and constant mixing speed. This allows mixing viscous liquids in a precise and controlled manner without excessive noise.

  • Easier setup with keyless chuck - no tools needed. Quick and easy one-handed head shank replacement. Special design saves lab workers time and reduces their workload.

  • The device is designed with safety in mind. A lock button prevents accidental speed changes, and motor overload detection technology stops mixing before an overload occurs, protecting the sample.

Detailed Features:

  • Display: Easy-to-read digital LED display with speed indication, current torque trend and built-in timer.

  • Programs: Mixing, dissolving, dispersion, emulsification and homogenization in food, cosmetics, paints/coatings, pharmaceuticals, chemicals, adhesives, plastics/polymers and cement/construction industries. Used in pilot-scale production.

  • Power: Mixing speed from 6 to 2000 rpm, accuracy of 1 rpm and maximum torque from 20 Ncm to 200 Ncm depending on the model, stable torque at any speed, capacity from 25 l to 100 l.

  • Communication: n/a.

  • Design: IP54-rated hermetic aluminum housing, keyless handle for easy one-handed operation, brushless motor for quiet operation, and master switch.

  • Design Features: Compact design for easy operation, simple knob control, lock button to prevent accidental changes in settings, full overload and over-temperature protection
